Transmog Post: The Unburnt

 I've been a bit obsessed with George RR Martin's A Song of Ice and Fire series, and it's TV show Game of Thrones. My favorite character is Daenerys, Mother of Dragons and the last of the Targaryen Dynasty. Half my toons are named after her and her family members.

One of her title is The Unburnt, which I thought would make a really cool RP type name for a DK. A Death Knight preserved by the fires of the Dragon Queen, similar to what happened (and which we don't know about...biggest kept secret on Azeroth...) to Bolvar Fordragon. Anyways, I started making an outfit based on fire, which was pretty easy considering Firelands, but in general, I never made an outfit I liked under this pretense.
This changed, however, when I started my warrior. While toying with gear that I liked, I found the perfect outfit that fulfilled what I was looking for. Although my warrior isn't called The Unburnt, I still think the outfit is pretty nice.

Helm: Jaw of Repudiation - Valor Point Vendor
Shoulders: Destroyer Shoulderguards - Tier 5 Token from Tempest Keep (Void Reaver)
Chest: Lifeforge Breastplate - BoE drop from Ulduar (Ignis the Furnace Master)
Gloves: Gauntlets of the Molten Giant - Tier 12 Cataclysm Justice Point Vendor
Belt: Girdle of Unyielding Trust - WotLK 226 ilevel Justice Point Vendor in Dalaran.
Pants: Legguards of the Molten Giant - Tier 12 Cataclysm Justice Point Vendor
Feet: Hellfrozen Bonegrinders - Blacksmithing Crafting 264 ilevel (Recipe from ICC Vendor)

The chest piece was a fluke. I lucked out on the AH one day. I like how its different and matches both the helm and the legs. I know the helm is supposed to be Deathwing-like, but I think it fits well.
